Your first request will be send to http://httpbin.org:80/test. And Because there is no request mapping for /test in http://httpbin.org, You got 404 Not Found response from http://httpbin.org.
Your second request will not be sent anywhere. "/test2" cannot be sent, because your route config is "/test". So you got 404 Not Found response from your gateway application. If you want to apply same routing rule to "/test2", your config have to be "/test**"
